To all 'whom .it may concern:

Be it known that I, THOMAS L. NEWTON,

a citizen of the United States, residing at Fresno, in the county of Fresno, State of California, have invented certain new and useful Improvements in Grease-Dispensing .Apparatus; and I do declare the following to be a Lfull, clear, and exact description of the same, such as will enable others skllled in the art to which it appertains to make and use the same, reference being had to the' produce a portable pump whichv will have a large carrying capacity and a suiiicient force to pump hard or soft grease ,in 'a rapid and eflicient manner. i

A further object of the inventionv is to produce a simpleand inexpensive device, and yet one which will be .exceedingly effective for the purposes for which it is designed. A.

These objects I accomplish by means' of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views.

Figure l is a side elevation of the complete pump. Fig. 2 is a vertical cross section of the same. Fig. 3 is a top plan view of the pump cylinder and operatingv gear. Fig. 4 is a rear elevation of the upper end of the pump cylinder and supports.

Referring now more particularly 'to the characters of reference -on the drawings I first provide side supporting members 1I kinder is splitat one point as at a to form a removable cap 6. The bottom of the plate 4 isprovided with a nozzle 7 adapted to receive a hose or flexible pipe 8 through which the grease will be pum ed to a nozzle 9 adapted to be inserted in t e part of the mechanism` which is to be lubricated, such as .transmission boxes, differentials, crank cylinders or any other part of the machinery to be lubricated.

Movable within the cylinder 5 is a piston 10 having a gear rack or rod 11 projecting through the cap 6 and movable through a guide' 12. mounted on side rods 13 hinged as at 14 to the bottom plate 4. The piston 10 has three rings 10a.

On the member 12 are projecting arms 15 carrying a gear wheel 17 engaging the rack 11 to lraise and lower the piston 10. Said ear wheel 17 is mounted on a shaft 18 pro- ]ecting through an arm 19 on one of the rods 13 on the outer end of which shaft 18 are two ratchet wheels 20 and 21 having their ratchets disposed in opposite directions. Also'mounted on the shaft 18 is an operating handle 22 having two dogs 23 and 24 adapt- Patented Jan. 23,1912;y Application led March 21, 1911.. Serial No. 615,954.

edto engage the ratchet wheels 20 and 21 respectively to lower or raise the piston 10. Each of these dogs 23 and 24 has a spring 25 lconnected by a link 26 with a lever 27 whereby either of said dogs may be engaged with its respective ratchet wheel as it is desired to raise or vlower the piston 10.

In operation the downward movement of the piston 10 will force the lubricant throu h the nozzle 7, hose 8 and nozzle 9 into t e mechanism to be lubricated.

When it is desired to ll the cylinder 5 with the lubricant the piston 10 is raised by means of the operatlon above described until it fits into the cap 6 and then it is continued to be raised Auntil it lifts the cap `6 clear of the cylinder 5 when the entire cap, piston and piston operating means may be inclined backward against the member 3 as shown in Fig. 2 by dotted lines and the cylinder 5 can then be filled as desired. This operation is permitted of by reason of the flexible connect-ion 14 of the rods 13, the operating mechanism being all connected von said rods 13, as above described. In order to permit the piston 10 to be readily raised I provide a cock 28 which may be opened to permit an intake of air as the piston 10 is raised which cock will of course be closed whenthe cylinder 5 is filled with lubricant.

Mounted on the member 12 is an eccentric cam 29 `having a handle 30, which cam is impinged against the lid 6 when the cylinder is .full in order to hold such lid 6 in porigid for use.

From the foregoin description it will readily appear that I ave produced sucha.N

device as will substantially fulil the objects of the invention as set forth herein.

While this specification sets fort-hv in detail the present and preferred construction` of the device,l still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention. f Having thus described my invention what I claim as new and useful anddesire to secure by Letters Patent, yis:-

V4said cap simultaneously from vsaid 'cylindla by'said o erat-ing means as described.

2. A evice of the character described comprising a base, a vertical cylinder on sald base, such cylinder having a removable cap, a piston movablelin said cylinder, a geared bar on said piston projectin through the top of said cap, vertical bars inged to said base and carrying a guide, said geared bar being movable through said guide; means for operating" said geared bar, 'an eccentric cam mounted 'on said guide and adapted to engage said cap, as described.

In testimon whereof I aiiix my signature in presence o two witnesses.
